The voltrx protein shaker has a perfect shape and is suitable for car cup holders.

　　The size of the protein shaker is good. The carrying hook is quite fragile, and the top cannot rotate freely, only half. nothing. Although, I believe the design of this gym water bottle will be 100% leak-proof!

　　Large capacity allows proper mixing when shaking-no lumps. Perfect before and after exercise and protein shakes. The lid is great and it is always closed.
